Vertisol has a clay texture, high micropores, and high water and nutrient absorption ability. The high water content of Vertisol causes the air to decrease, thus inhibiting root development. Stretching of the Vertisol structure is expected to increase soil porosity and reduce ion and water absorptio...

Ultisol soil has a low organic matter content, CEC, and pH, causing an insufficient buffering capacity for N nutrients, especially NH4+. The objective of this study was to determine the effect of tillage and fertilization on the quantity and intensity (Q/I) of Ammonium (CRNH40, PBCNH4+, NH40, KG) in...
